To all whom it may concern:

. Be it known that we, THOMAS W. BELL and THOMAS- 0. Rooms, citizens ofthe.

United States, residin at Sistersville, in the county of Tyler, tate ofWest Virginia, have invented a new and useful Wire- Line Clamp, of whichthe following is a specification. i v

The deviceforming the subject matter of this application is ada' ted tobe used for gripping cables of the kind used in well drilling, and oneobject of the. invention is to improve generally and to enhance theutilthe cable.

A further object of the invention is to provide novel means for holdingthe grips in the jaws. I

The invention contemplates the provision of means whereby the link maybe set free,

-to afford-some play, when the jaws are open. I v j But one form of theinvention/is shown in the drawin s, and it is to be understood 1 that,within t e scope of what is'claimed,

a mechanic maymake changeswithout departing from the spirit of theinvention.

In the accompanying drawings Figure 1 shows in rear elevation, a deviceconstructed in accordance with the invena side elevation; Fig. 4 is asection on the line 4-4 of Fig. 3; Fig. 5 is a fraginental perspectiveshowing parts of one .of the jaws; and Fig. 6 is a perspectivedisclosing the retainer which holds the grip in the aw.

provided a pair of jaws 1 provided with hooks 26 at their upper ends,the hooks being adapted to recelve the usual hoisting rings 27. In theinner edges of the jaws 1, dovetailed recesses 2 are formed, and into tocooperate. The jaws 1 are supplied upon- Specification of LettersPatent.

In carrying out the invention there is their rear sides with transverseribs 6 which project beyond the bases of the recesses 2 and serve toprevent the grips 3 .from slid- Patented July 8, 1919. Application filedOctober 21, 1918. Serial No. 259,010. I

The jaws 1 are provided with rearwardly extended lugs 8 which project,as shown at 9 in Fig.5 beyond the bases of the recesses 2 and aid inholding the grips 3 in the recesses 2, against rearward movement. Arms10. project -forwardly from thejaws 1 and are supplied with seats ornotches 11. Angular retainers 12 are provided, the same including, each,a transverse part 14and a longitudinal part 15. The transverse parts 114of the retainers 12 rest on top of the arms 10, the longitudinal parts15 of the re- 7 tainers being received in the seats or notches 11,- andengaging the forward edgesv of thegrips 3 to prevent the grips frommoving forwardly- The grips 3, therefore, are held in the dovetailedrecesses-2, without the use of set screws or like devices,but,'by-removing the retainers the grips 3 may be renewed;

at any time. The parts 14 of the retainers 12, and the arms 10aresupplied with openings 16, adapted to receive securin devices 17,whereby the retainers 12 are he d on the arms, in a way, which will beunderstood clearly when Figs. 4. 3 and #2 are examined.

The rearwardly extended lugs 8 are sur rounded by' a continuousloop-shaped-link 18, the lugs havin projections 19 which cooperate withthe ink to hold the link onthe lugs. The link 18 is equipped withrearwardly extended ears 20, having curved or eccentric outer edges,coacting with the projections 19.

The forward ends of the'arms 10 are received within a U-shaped yoke 21,the ends of the arms of the yoke being united by a pivot element 22,with one of the arms 10,

8 are fulcru'medon the link 18, the rojections 19 being engaged with thecurve outer edges of the ears 20 so as to hold the link 18 in placeagainst the jaws 1. The screw 24 is advanced, the outer ends of the armsinpro er relation to each other during the mounting of the structure onthe cable 5. In: order to release the hold of the grips 3 on the cable5,'the screw 24 may beretracted and, if desired, the yoke 21 may beswung on the pivot element 22, off that arm where- With the screwcooperates.

Since the link 18 is continuous and loopshaped, the link will have greatstrength, and will not open during the gripping operation. When theprojections 19 ride on the extended ears 20, the link 3 is heldrelatively close to the jaws 1', and, consequently,

the grips 3 have a stronghold on the cable 5, when the outer ends of thearms 10 are pressed toward each other by the action of the screw 24. Ashas been stated, the grips 3 may be released for renewal, by removingthe an lar retainers 12, set screws and th like being renderedunnecessary-r 1 Havlng thus described the'invention, what is claimedis 1. In a device-of the classdescribed, '00-] operating jaws havingrearwardly extended lugs and forwardly extended arms, a continuous .loop-shapedlink disposed transversely of the lugs and parallel to the jaws,the lugs passing through the link; means on the lugs for retaining th ithereon; and J an adjustable tightening device conn gc the arms.

2. In a device of the class described, "co- 7 operating jaws havingrearwardly extended 1 lugs and forwardly extended arms; a continuousloop-shaped link disposed transversely of the lugs and parallel tothe-jaws,

the lugs passing through the link; means on the lugs for retaining thelink thereon, the

rear face of the link being provided with eccentric parts cooperatingwith said means; and a. tightening device connecting the arms.

3. In a' device of the class described, '00- operatin jaws havingrecesses in their inner edges, the jaws having rearwardly extended lugsand being provided with forwardly extended arms,- the.jaws havingrearwardly extended ribs projecting beyond the bases of the recesses;removable retainers on the arms; grips in the recesses and held thereinb the projecting, portions of the ribs and y the retainers; means forpivotally connecting the ribs of the respective jaws; a link receivingthe lugs; and a tightenin means connecting the arms.

4. n a device of the class described, cooperating jaws equipped ;withrecesses in their inner edges, the jaws having rearwardly extended lugs,andbeing provided i with forwardly extended arms, the jaws havingrearwardly extended ribs which project beyond the bases of the recesses;removable retainers on the arms; grips in the recesses and held thereinby the projecting portions of the ribs and by the retainers; a linkreceiving the lugs; and. a tightening means connecting the arms.

In testimony that we claim the foregoing as our own, we have heretoaflixed our signatures in the presence of two witnesses.
